Baltimore County is a county in the U.S. state of Maryland. It is Maryland’s third-most populous county. It hosts a diversified economy, with particular emphasis on government, education and health care. Much of Baltimore County is suburban, straddling the border between the Piedmont plateau to the northwest and in the southern and southeastern regions of the county bordering the Patapsco River and the Chesapeake Bay, the Atlantic coastal plain. Northern Baltimore County is primarily rural, with a landscape of rolling hills and deciduous forests characteristic of the Southeastern mixed forests and shares the geography with its neighbors to the east and west, Carroll County and Harford County, and going north across the historic Mason–Dixon line into Adams County and York County in south-central Pennsylvania.

 

The county is home to multiple universities including the University of Maryland, Baltimore County; Towson University; Goucher College and Stevenson University (formerly Villa Julie College). All public schools in Baltimore County are operated by Baltimore County Public Schools, with the exception of the Imagine Me Charter School which opened August 2008.
